Determine if String Halves Are Alike - LeetCode

더하고 빼기만 잘하면 되는 문제. lowercase로 바꿔도 상관 없어서 걍 바꿔서 처리함

class Solution:
    def halvesAreAlike(self, s: str) -> bool:
        s = s.lower()
        vowels = ['a', 'e', 'i', 'o', 'u']
        l, h, cnt = len(s), len(s) // 2, 0         
        
        for i in range(l):
            if s[i] in vowels:
                if i < h:
                    cnt += 1
                else: 
                    cnt -=1
        
        return cnt == 0
